actually... it would make sense to me if the client code just went ahead
and tried the install, even if the ping failed.  the reason we added
the ping was to make some switches aware of our existance, iirc.

i just committed this patch - Brian: feel free to revert if you
disagree.

Dan: anyway, this code is in /etc/init.d/functions, in the
initrd.img file.  you need to crack it open, copy the contents elsewhere, 
make your change & regen a new initrd.img.

something like this:

cd /usr/share/systemimager/boot/i386/standard
cp initrd.img initrd.img.bak
gunzip < initrd.img > initrd
mkdir /mnt/tmp
mount initrd /mnt/tmp -o loop
mkdir /tmp/initrd
cp -a /mnt/tmp/* /tmp/initrd
cd /tmp/initrd
<make your changes in this tree>
mkinitrd /tmp/initrd /tmp/initrd.img
cd -
mv /tmp/initrd.img .
